So Can Viagra Cause Blindness?

American researchers deny the claim that the use of drugs against erectile disorder, such as Viagra, can lead to poor eyesight. Still, some men who took these drugs complained to doctors about vision impairment. For example, they reported that they see objects in blue or purple colors.

To test how dangerous Viagra is to the eyesight, the experts at the Indianapolis Research Laboratory conducted research in which approximately 200 men took part. All the participants underwent a comprehensive eye examination to compare the state of their vision before and after the experiment. During six months, the men were divided into 2 groups, one of which took Viagra drugs and the other took placebo medications. At the end of the study, there was no significant difference in vision change between patients who used drugs to treat erectile dysfunction and those who took the placebo.

The very mechanism of Viagra’s action is based on the narrowing of certain arteries. In people who have a corresponding predisposition, taking a pill can provoke insufficient blood supply to the optic nerve. That is why in some people the reception of Viagra is accompanied by temporary visual impairments, including for example, the distortion of perception of green and blue.

Talking about risks, it is necessary to mention that a lot of research shows the same result. There is some kind of risk of developing eye problems after taking the drug. But it usually happens only if a user is someone who has risk factors for developing this problem.

Viagra may affect the eyesight of men with eye problems. The scientists tested sildenafil on healthy mice and on mice with a mutant gene. The medication affected the vision of mice that carried the mutant gene for two weeks. So, sildenafil could cause unusual visual responses in people who carry a common mutation for eye disease.

Doctors give the warning that some drug components may affect eyesight and lead to loss of vision in patients with retinitis pigmentosa. It is a rare inherited eye condition that causes loss of eyesight. Some people have normal vision but carry one gene for the condition. So, people with this disease and those who carry the gene are at an increased health risk.

Does Cialis Have Such Side Effects on Eyes?

Different concerns expressed by doctors from various countries of the world were groundless: permanent long-term use of Cialis does not affect a man’s vision. This fact was established by an international team of researchers.

These fears arose after some drug consumers complained of short-term blurred vision and dark spots before their eyes. Since the action of Cialis is based on the blocking of a certain enzyme in the bloodstream in the genital area, physicians began to suspect that the drug can also act on similar enzymes in the retina of the eye. However, it turned out that this is not so.

This information concerns all oral ED medicines. In any case, patients should consult with their doctors on how to use Cialis and follow the drug’s prescription information, the same as with any other medicine.

Where to Buy Proven Viagra and Cialis?

During the many years that Viagra has been on the market, it has been consumed by almost 27 million Americans. The pharmaceutical companies’ specialists did not observe a single case of vision loss in patients. This means that the risk of visual impairment, if any, is extremely small.

Erectile dysfunction drugs have undergone a lot of tests and proved their usefulness and helpfulness combating men’s problems. It can be stated for sure that this treatment is completely safe, but it should be taken with certain precautions.
